Karymsky volcanostratovolcano 1536 m (5,039 ft)
Kamchatka, 54.05°N / 159.43°E Current status: minor activity or eruption warning (3 out of 5) Karymsky webcams / live data
last update: 24 May 2012 (possible small ash eruptions, thermal anomaly at summit crater)
Typical eruption style: Doninantly explosive, construction of lava domes, near constant activity. Karymsky volcano eruptions: 1771, 1830, 1852, 1854, 1908, 1911, 1912, 1915, 1921, 1923, 1925, 1929, 1932, 1933, 1934, 1938, 1940, 1943, 1945, 1946, 1947, 1952, 1953, 1955, 1956, 1960, 1965, 1967, 1970, 1982, 1983, 1985, 1990, 1993, 1996 - ongoing Karymsky volcano photos Background:Much of the cone is surrounded by lava flows no older than 200 years. Historical eruptions have been vulcanian or vulcanian-strombolian with moderate explosive activity and occasional lava flows from the summit crater.The cone has been constructed during the past 2000 years within a 5-km-wide caldera that formed about 9,000 year ago within a complex system of overlapping calderas. The caldera cuts the south side of the older Dvor volcano and is located outside the north margin of a large, still older caldera (the mid-Pleistocene Polovinka caldera), which contains the smaller Akademia Nauk and Odnoboky calderas. Most seismicity preceding Karymsky eruptions originated beneath Akademia Nauk caldera, which is located immediately south of Karymsky volcano. --- Source: GVP, Smithsonian Institution Karymsky Photos:
